5 0

Answer:

A. Neon and argon

General Formulas and Concepts:

  • Reading the Periodic Table of Elements
  • Valence Shell configurations

Explanation:

Elements that have a full valence shell (the outermost shell), are in Group 18 of the Periodic Table.

Because their outermost shell is full, they are inert, meaning that they do not like to bond or react with other elements.

Therefore, these gases with a stable full valence shell are known as Noble Gases.

  1. Helium
  2. Neon
  3. Argon
  4. Krypton
  5. Xenon
  6. Radon

A. would be the correct answer.

A proton is moving toward a second, stationary proton. What happens as the protons get closer?
MatroZZZ [7]

Answer:

A. Kinetic energy is converted to electric potential energy, and the proton moves more slowly.

Explanation:

When a moving proton is brought close to a stationary one, the kinetic energy of the moving one is converted to electric potential  and the proton moves more slowly.

Kinetic energy is the energy due to the motion of a body. A moving proton will possess this form of energy.

Two protons according to coulombs law will repel each other with an electrostatic force because they both have similar charges. This will increase their electric potential energy of both of them.

Potential energy is the energy at rest of a body. As it increases, the motion of a body will be slower and it will tend towards being stationary.
